Questions tagged [echo]

Simple function outputting text. Exists in script languages.

echo is mainly used in batch (cmd). An example would be:

echo hello world

which prints "hello world" to the terminal.

The output by default prints directly to the command line, however, it may be piped into a following command as an input. This can be very handy and allows for interoperability between different processes/languages.
